DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 398,763, dated February 2G, 1889.

Application tiled August 10, 1888. Serial No. 282,426. tNo model-5 T0 @ZZ whom t may conce/v1.:

Be 1t known that I, OWEN T. BAKER, a citizen of the United States, residing at Fort WTOrth, in the county of Tarrant and State g of Texas, have invented new and useful Improvements in Door and Window Stops, tt which the following is a specification.

The object of my invention is to provide a cheap, effective, and easily-operated doorstop in which the parts are so constructed and arranged as to be unlikely7 to need repair.

The invention consists in a cert-ain novel operatin g mechanism. Fig. 3 is a similar view with the bolt raised. tral sectional view of the stop on the line :r :r of Fig. 2.

Referring by letter to the drawings, A designates the casing of the doorstep, which is secured to the door by means ot screws or similar means, and in this casing is arranged the vertically-inovable bolt B, in the bifurcat-ed lower end of which is mounted the eccentric halt or whole roller or rocker C, with a rubber band, the loop of which is designed to bear on the floor when the door is to be stopped. The rear side ot' the casing is provided with a stud or projection, D, which eX- tends forwardly into a groove, E, in the rear side of the bolt, and in this groove is arranged a spiral spring, F, which bears at its lower end on the said stud or projection and at its upper end against the upper end of the groove, whereby the boltis normally held raised, as shown in Fig. 3 of the drawings.

A wedge-plate, G, is afxed to the front side of the bolt within the easing, (the outer edge of the said plate being flush with the side of the casing and the inner side being inclined,) and H represents a catch or slide which is mounted on the bolt and extends at its upper end to the upper end of the same. The catch or slide is provided near its upper end with a Fig. i is a vertical cenvertical slot, 71, which slides on a screw or stud, I, on the bolt, and the upper extremity of the catch or slide is provided with a toehold, l-l, whereby the latter may be manipulated. The outer edge of this catch or slide bears against the opposite side ot the easing Vfrom the wedge-plate G, and it is tapered toward its lower end, so that its inner edge is parallel with the inner or adjacent edge of the wedge-plate- K represents an adjustable bar which is arranged between the adjacent parallel edges of the wedge-plate and the catch or slide, and the upper end of this bar is provided with a pin, lo, which slides in a transverse guide-slot, L, in a suitable plate, M. It will be seen that this bar is thus prevented from moving vertically, but is allowed free lateral movement.

When the catch or slide is raised, as shown in Fig. 3,with the stud or screw lin the lower end of the slot 71, the distance between the parallel edges of the wedge-plate and catch or slide is sutlicient, when the bolt is pressed down, to allow the adjustable bar to move laterally toward the wedge-plate to permit the catch or slide to pass up; but when the downward pressure on the boltis removed and the bolt is allowed to move upward slightly by the force of the spring l? the wedge-plate will also move upward, whereas the catch or slide will remain stationary, and therefore, the distance between theadj acen t sides of the wedgeplate and t-he catch or slide being reduced, the adjustable bar will be clamped tightly therebetween and the bolt will be locked in position. ltrequires only a very slight vertical movement ot the bolt to eitect this lock, as will be evident; but if it is desired to lock the bolt immediately it is only necessary to press the catch or slide down while the bolt is held in the desired place without permitting the latter to return.

In order to insure a more immediate locking of the bolt on its being pressed down to the floor, the adjustable bar is preferably tapered slightly toward its lower end, as shown in the drawings.

The operation of this device will now be readily understood. To lock the door in a desired position, press downward with the foot on the upper end of the bolt, and to release IOO 'the door raise the catch or slide by pressing' the toeahold upward.

The rubber band on the eeeent-re roller enables the device to obtain a rm hold on the floor. This device may with equal effectiveness be used in connection with windows, as will be readily seen.

Having thus deseribed the invention, I elainil. In a door-stop, the combination, with a sliding belt provided witha wedge-plate, of the longitudinallymovable catch or slide mounted on the bolt and the laterally-movable bar located between the adjacent sides of the wedge-plate and eateh or slide, substantially as specified.

2. In a door-stop, the combination, with the sliding bolt provided with a wedge-plate, G,

. of the longitudnally-inovable catch or slide having one of its edges adjacent to and par` allel with the wedge-plate and the adjustable bar located between the adjacent edges of the wedge-plate and Catch or slide and provided with a pin sliding in a suitable guideslot, substantially as specified.

3. In a door-stop, the combination, with a 4. In a door-stop, the combination, with the spring-actuated sliding bolt provided with a wedge-plate, G, of the tapered Catch or slide H, provided, with a toe-hold, I'I, and the adj ustable bar K, arranged between the wedge` plate and the catch or slide, substantially as specified.

In testimony that I elam the foregoing, as my own I have hereto affixed my signature in presence of two witnesses.
